  • How can I guess if a USB cable will power my devices?

    - by rsanchez
    I've had problems with one long (4 meter) USB Mini-B to USB Type-A cable not being able to boot a 2.5'' external hard disc due to not supplying enough current. On top of that, the cable used a Type-A to Mini-B adapter for the Mini-B part, which probably made things worse. Three different shorter cables I got around made the hard disk work without extra current, so it was definitively the cable's fault. However, if I plugged the hard disk to the power, and used the long cable just for data it worked. Here is some related information on powering through USB cables: http://www.girr.org/mac_stuff/usb_stuff.html I have not any long cables that don't have an intermediary Type-A to Mini-B adapter to try them out. My question is: is there a way to guess if a cable will provide enough power for charge/disk drive power? Is it related to the length of the cable, to the build quality of the cable, or the fact that uses intermediary adapters?

  • Need Boxee/Vista remote control recommendations

    - by gurun8
    I have an Acer Aspire X1200 (specs link below) desktop computer that I've installed Boxee on and it works great. And it looks like it's going to be a perfect computer for a media player. It's small with lots of hard drive space and even has a HDMI output on it. http://support.acer.com/acerpanam/desktop/0000/Acer/AspireX1200/AspireX1200sp2.shtml I also have a Harmony® 880 Advanced Universal Remote (specs link below) that I'd like to use with the Acer computer. www.logitech.com/en-us/440/372 My thought is that I need to get a USB remote control adapter, right? So I did a quick Google search and found products from $5 to hundreds of $$$. Does anyone have recommendations? Things you like/dislike about certain remotes? This Acer is running Vista and has a AMD LIVE!: Athlon X2 dual-core processor. 64 bit some times makes it a little more difficult. Thanks for the help.

  • A terminal emulator for ex-Windows users

    - by Dan
    There are several things I would like to be better in Ubuntu Terminal Emulator. coloring, like in the source code Copy and paste keyboard shortcuts that I used all the time in Windows: Ctrl-C and Ctrl-V (Most of people here in Ubuntu use Ctrl+C and Ctrl+V keyboard shortcuts to copy and paste everywhere except the terminal! I think it's annoying for newcomers, and I don't worry about historical reasons) A feature to save all the output to log file UPDATE: Can the terminal be a powerful feature-full user-friendly tool like a modern IDE? The Linux user can spend 30% of time in the terminal. Programmers no longer code in a notepad. Can I see the history pane? Suggestions? Directory pane? Commands list? Search for words in an output? Contextual behavior? "Search in Google" for a mouse right-click. Tips and tricks learning? Time is money! Please, people, give me a link to the 21st - century terminal.

  • Benefits of Server-side Coding

    There are numerous advantages to server scripting languages over client side languages in regards to creating web sites that are more compelling compared to a standard static site. Server side scripting are scripts that are executed on a web server during the compilation of data to return to a client. These scripts allow developers to modify the content that is being sent to the user prior to the return of the data to the user as well as store information about the user. In addition, server side scripts allow for a controllable environment in which they can be executed. This cannot be said for client side languages because the developer cannot control the users’ environment compared to a web server. Some users may turn off client scripts, some may be only allow limited access on the system and others may be able to gain full control of the environment.  I have been developing web applications for over 9 years, and I have used server side languages for most of the applications I have built.  Here is a list of common things I have developed with server side scripts. List of Common Generic Functionality Send Email FTP Files Security/ Access Control Encryption URL rewriting Data Access Data Creation I/O Access The one important feature server side languages will help me with on my website is Data Access because my component will be backed with a SQL server database. I believe that form validation is one instance where I might see server-side scripts and JavaScript used interchangeably because it does not matter how or where the data is validated as long as the data that gets inserted is valid. However, I would have to say that my personal experience would have to sway me in deciding what type of languages to use for form validation because they both have advantages and disadvantages based on the each situation.

  • ubuntu pptp connections from command line

    - by Ian R
    I'm using a lot of vpn connections daily for my work and I want to program a pptp dialer in python to ease my job a little bit by automating things. I usually go with network-manager-pptp to setup my connections but I would like to skip this gui tool and do it from the script. Something like a dialer. My question is. Can pptp connections be established using the command tools only? Also, where does network-manager-pptp saves its failes so I can take a look and see what configs it generates. Any help is much appreciated.

  • Free Markdown JS viewer

    - by maaartinus
    I'd like to use Markdown for documents to be exchanged with a colleague of mine. The ideal workflow would be IMHO editing the source in any plaintext editor while simultaneously viewing it in a browser. The client viewer should be able to redraw the text after each save automatically, and ideally even always switch to the most recent source file (so I don't need to navigate there manually). It'd be nice if I could (was allowed) modify the viewer a bit, things like using trailing spaces for line breaks are really terrible (I don't see them, my editor strips them, git complains about them, etc.). I'm interested in a software capable of this and easy to modify, and also in your opinions on the described workflow.

  • Is an app that does nothing but link to a web site functional enough to meet Apple's iOS guidelines?

    - by Pointy
    I don't hang out on Programmers enough to know whether this question is "ok", so my apologies if not. I tried to make the title obvious so at least it can be closed quickly :-) The question is simple. My employer wants "home screen presence" (or at least the possibility thereof) on iOS devices (also Android but I'm mostly interested in Apple at the moment). Our actual application will be a pure web-delivered mobile-friendly application, so what we want on the homescreen is basically something that just acts as a link to bring up Safari (or Chrome now I guess; not important). I'm presuming that that's more-or-less possible; if not then that would be interesting too. I know that the Apple guidelines are such that low-functionality apps are generally rejected out of hand. There are a lot of existing apps that seem (to me) less functional than a link to something useful, but I'm not Apple of course. Because this seems like a not-too-weird situation, I'm hoping that somebody knows it's either definitely OK (maybe because there are many such apps) or definitely not OK. Note that I know about things like PhoneGap and I don't want that, at least not at the moment.

  • Is it possible to use the IE10 App without making Internet Explorer the default browser?

    - by nhinkle
    Windows 8 comes with two versions of Internet Explorer: the normal desktop version, which looks just like IE9, and the Modern UI version, which is a full-screen tablet-style app. By default, links opened in desktop mode open in desktop IE, and links opened in Modern UI apps open in the full-screen app. When you set a new default browser (like Google Chrome, which has a Modern UI mode now), you can no longer access IE10 in the Modern UI at all - the tile disappears from the start screen, and there's no way to manually invoke it. I don't use IE10 much, but I'd like to have access to it in Metro mode, because it's handy for testing things out. I don't want to have IE be my default browser though. Is there any way to get the IE10 "App" to show up without setting IE to be the default browser everywhere?

  • Can Dungeons & Dragons Make You More Successful? [Video]

    - by Jason Fitzpatrick
    Dungeons & Dragons gets a bit of a bad rap in popular culture, but in this video treatise from Idea Channel, they propose that Dungeons & Dragons wires players for success. There are some deeply ingrained stereotypes about Dungeons & Dragons, and those stereotypes usually begin and end with people shouting “NERD!!!” But the reality of the D&D universe is a whole lot more complex. Rather than being an escape from reality, D&D is actually a way to enhance some important real life skillz! It’s a chance to learn problem solving, visualization, interaction, organization, people management… the list could go on and on. Plus, there are some very famous non-nerds who have declared an affinity for D&D, so best stop criticizing and join in if you want to be a successful at the game of life. While we’re trying not to let our love of all things gaming cloud our judgement, we’re finding it difficult to disagree with the premise that open-ended play fosters creative and adaptive thinking.

  • What can be done against language inertia?

    - by gerrit
    Often, projects use programming language X, but would use programming language Y if they were started from scratch. For example, big numerical models may be written entirely in Fortran. Whereas this might be a reasonable choice for the components that need to run fast (alternative would be C or C++), it might be a poor choice for components that either do not need to run fast (such as things dealing with human input or simple visualisations), or where runtime is not the limiting factor (such as I/O, particularly when from the network). Another example may be when a project is built using a propriety language (such as Matlab; no, FOSS clones are not good enough) and was started at a time when FOSS alternatives were not viable, but ten years later, they are; and it would be beneficial to migrate. However, due to language inertia, a migration does not happen. Code that works should not be touched, porting code is a time-consuming, expensive process, and programmers are familiar in language X but not necessarily in language Y. Still, in the long term, a migration would likely be beneficial. Can anything be done to mitigate the problems associated with language inertia? Are there any notable examples of big projects that have successfully overcome this problem? Or is a project bound to stick forever with the initial choices?

  • Languages like Tcl that have configurable syntax?

    - by boost
    I'm looking for a language that will let me do what I could do with Clipper years ago, and which I can do with Tcl, namely add functionality in a way other than just adding functions. For example in Clipper/(x)Harbour there are commands #command, #translate, #xcommand and #xtranslate that allow things like this: #xcommand REPEAT; => DO WHILE .T. #xcommand UNTIL <cond>; => IF (<cond>); ;EXIT; ;ENDIF; ;ENDDO LOCAL n := 1 REPEAT n := n + 1 UNTIL n > 100 Similarly, in Tcl I'm doing proc process_range {_for_ project _from_ dat1 _to_ dat2 _by_ slice} { set fromDate [clock scan $dat1] set toDate [clock scan $dat2] if {$slice eq "day"} then {set incrementor [expr 24 * 60]} if {$slice eq "hour"} then {set incrementor 60} set method DateRange puts "Scanning from [clock format $fromDate -format "%c"] to [clock format $toDate -format "%c"] by $slice" for {set dateCursor $fromDate} {$dateCursor <= $toDate} {set dateCursor [clock add $dateCursor $incrementor minutes]} { # ... } } process_range for "client" from "2013-10-18 00:00" to "2013-10-20 23:59" by day Are there any other languages that permit this kind of, almost COBOL-esque, syntax modification? If you're wondering why I'm asking, it's for setting up stuff so that others with a not-as-geeky-as-I-am skillset can declare processing tasks.

  • How can I improve my isometric tile-picking algorithm?

    - by Cypher
    I've spent the last few days researching isometric tile-picking algorithms (converting screen-coordinates to tile-coordinates), and have obviously found a lot of the math beyond my grasp. I have come fairly close and what I have is workable, but I would like to improve on this algorithm as it's a little off and seems to pick down and to the right of the mouse pointer. I've uploaded a video to help visualize the current implementation: http://youtu.be/EqwWcq1zuaM My isometric rendering algorithm is based on what is found at this stackoverflow question's answer, with the exception that my x and y axis' are inverted (x increased down-right, while y increased up-right). Here is where I am converting from screen to tiles: // these next few lines convert the mouse pointer position from screen // coordinates to tile-grid coordinates. cameraOffset captures the current // mouse location and takes into consideration the camera's position on screen. System.Drawing.Point cameraOffset = new System.Drawing.Point( 0, 0 ); cameraOffset.X = mouseLocation.X + (int)camera.Left; cameraOffset.Y = ( mouseLocation.Y + (int)camera.Top ); // the camera-aware mouse coordinates are then further converted in an attempt // to select only the "tile" portion of the grid tiles, instead of the entire // rectangle. this algorithm gets close, but could use improvement. mouseTileLocation.X = ( cameraOffset.X + 2 * cameraOffset.Y ) / Global.TileWidth; mouseTileLocation.Y = -( ( 2 * cameraOffset.Y - cameraOffset.X ) / Global.TileWidth ); Things to make note of: mouseLocation is a System.Drawing.Point that represents the screen coordinates of the mouse pointer. cameraOffset is the screen position of the mouse pointer that includes the position of the game camera. mouseTileLocation is a System.Drawing.Point that is supposed to represent the tile coordinates of the mouse pointer. If you check out the above link to youtube, you'll notice that the picking algorithm is off a bit. How can I improve on this?

  • ADF Faces Skin Editor - How to Work with It

    - by Shay Shmeltzer
    The ODTUG Kscop11 conference was a great success with lots of sessions about FMW running in a special track. I did several sessions and labs in the conference, and I thought it might be a good idea to at least give you a taste of what you might have missed. So here is most of what I demoed in my ADF Faces Skinning session (not all though - that session was 60 minutes long, and while everyone did end up going out of the building in the middle because of a fire drill for about 5 minutes, there was other things covered in the session as well). In the demo here you'll see how to generate new images and default color scheme, how to identify a component class with Firebug, how to skin a component, how to identify the global selector of a property, how to change fonts and how to change strings. By the way, for more on ADF Skinning you should also listen to the ADF Insider seminar that Frank Nimphius recorded on skinning, it will give you better understanding of the overall skinning process. P.S. in the demo I add an entry to the web.xml file which prevent ADF Faces from compressing the HTML that is generated. The entry is for org.apache.myfaces.trinidad.DISABLE_CONTENT_COMPRESSION  and I set it to true. This is very useful when you work on creating the skin, but don't forget to un-set it before you go production.

  • Wired connection problem through router

    - by tommypincha
    I'm having trouble to connect my Ubuntu 11.10 to internet through ethernet. I installed a router to get Wi-Fi and now (by a wired connection) I can't have internet with ubuntu (but I can with Windows 7). I see several attempts per minute of the network-manager to get a connection, but after a minute it stops trying. Here are a couple of outputs from key files: cat /etc/network/interfaces auto lo iface lo inet loopback and ifconfig -a eth0 Link encap:Ethernet HWaddr 00:16:76:e4:a6:e8 inet6 addr: fe80::216:76ff:fee4:a6e8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:117 dropped:0 overruns:0 frame:117 TX packets:50 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:12221 (12.2 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:582 errors:0 dropped:0 overruns:0 frame:0 TX packets:582 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:46024 (46.0 KB) TX bytes:46024 (46.0 KB) I tried reconnecting the modem and the router and reconnecting the ethernet cable but nothing... I tried other solutions from other posts (this one has a similar issue Wired connection not working) but again nothing. My IP is dynamic. A couple of things I see and did: I see no inet addr, only inet6. I ignored ipv6 from the internet connections, and restarted the network-manager service and nothing. A difference with the post I mentioned is the RX packets with errors I have, is this a clue of the problem? Any help would be appreciated, Thanks!

  • Vim - dynamic list of open buffers in a window

    - by asfallows
    I've investigated a few ways to maintain a list of open buffers in Vim, and some of them are very good, but none of them seem to behave the way I'd like. It's very possible that nothing like what I want exists, and it can't hurt to ask. I've been using NERDTree in GVim, and I like the idea of putting the information in a slender left-hand window. I've put together a handy diagram for how I'd like my environment to look: |--------|---------------------------------------| | | | | | | |NERDTree| Windows | | | | | | | | | | |--------| | | | | | | | | List | | | of | | | Open | | | Buffers| | | | | | | | |--------|---------------------------------------| So my question is: Is there a vim-native or plugin-enabled way to maintain a list of currently open buffers and select/edit/close from that list, inside a window similar to NERDTree? I understand that this approach may be incongruous with the Vim way of doing things, and if you feel like I'm missing something about how to manage multiple files in a Vim session, please leave a comment with suggestions!

In the previous two sections I have discussed on how I got a CMMI v4.2 to take on the same fields as v5 and therefore be able to communicate with MTM and Lab Manager.  And that was quite a success. Yet when I opened up Lab Management while it was fully aware of the VMs being there, it refused to let me enroll them into an environment.  It kept stating there was no suitable host to deploy the VM to, error TF259115. This was an indication something was not matching the expected network configuration between TFS and Hyper-V/SCVMM. So, here are a couple of things that took place: Verified the network segment specified for network isolation matched what was configured physically for either DHCP or manually assigned IP addressing for the guest VMs Made sure TFS was fully aware of the configuration settings for the network location name.  For that I issued:  tfsconfig lab /settings /networklocation:”<name of the network location configured in SCVMM” On that last item, that was key to making sure Lab Management communicated with the VMs and for it to allow enrollment into the new Virtual Environment.

  • Installing BURG (NO MBR!)

    - by StepTNT
    I'd like to install BURG but I don't want it to overwrite my MBR. That's because I've got two bootloader in my system : 1) Default Windows 7 bl in my MBR 2) Grub in /dev/sda2 With the first power button, it will boot as Grub is not installed, so it simply loads Windows, with the second button it boots from /dev/sda2, loading Grub and then Kubuntu. Now I want to replae Grub with Burg. I've installe Burg with burg-install /dev/sda2 --force because I don't want my MBR to be overwritten (pressing the first power button MUST load Windows and avoid showing any sign of Linux things). Setup was completed without errors, and everything seems to work fine : if I open burg-manager it loads my settings, allowing me to change them and to test everything with burg-emu (that works as I want to). So, everything seems fine, Burg's installed, I've changed my settings but.. If I use the second power button, it still loads Grub! (Even a different version from the default Kubuntu one). So, here's the question : How can I replace GRUB that's on /dev/sda2 with BURG and WITHOUT writing it to my MBR? Thanks :)

  • USB drive is empty in drive management

    - by Simon Verbeke
    I've got a USB drive here, that somebody asked to try and fix. When inserting it, it shows up in explorer, but when I double click it I get a message saying "Please insert a disk into drive H:". So I went to disk management, to see if it was correctly formatted. It doesn't show up in the upper pane, and in the lower pane it tells me there is no medium in H:. After this I used chkdsk: the path is invalid. Then I tried TestDisk, which is supposed to look at raw data, and this can't even find the disk. So I'm assuming the drive is dead, even though its LED is burning. But I was wondering if there might be something else I could try? This system is Windows 7 Ultimate 64bit by the way. (I'm translating things from a Dutch install, so some names might be wrong)

  • Click buttons on the mouse stopped working in 12.10

    - by Kushal
    everything was great for a couple weeks after the upgrade, and then all of a sudden, the click buttons on my trackpad (as well as any other USB mouse I would hook up) stopped working. The pointer moves fine, but the clicks don't work. Sometimes the left click doesn't work but right click does, and then some times, neither works. I noticed this would begin when I would accidentally drag some text in a web browser (you know how when you try to move your pointer through the trackpad, but you accidentally tap down and it starts to drag whatever text you've selected on the window), and then you're done. The clicks won't work after that. They would work upon rebooting or logging off and back on, but then after a few minutes of usage, things would go back to being broken again. It happened a LOT when I was trying to play Scrabble on Facebook. I've raised a bug for this, but I haven't heard back anything on it. Here's the bug report: https://bugs.launchpad.net/bugs/1077805 Since the system was unusable this way, I had to remove it and install another OS based on 12.04. Has anyone else faced this issue or does someone know what to do to fix it? I'd go back to vanilla Ubuntu in a heartbeat if this issue can be fixed.

  • Is it recommended to use more than one language at a startup?

    - by GoofyBall
    I work for a mobile startup where, for historical reasons, our chosen language was C#. I was recently assigned to a small project to build a tool that would be used by us internally. When I explained my intention to use Python to build this tool I was heavily criticized for this because introducing new languages, and technologies (Debian, Apache, Python and Django) into our ecosystem would make it harder for other developers to maintain (because only two other people know more than one language besides C#). I countered that this project would take far longer to develop in C# (which I think is an inherent problem with the language/.NET framework) and that the project was small and designed to solve a very particular problem. Of course it is necessary that the ecosystem be as a homogeneous as possible but if your are developing tooling, infrastructure, and internal systems when there are better things to build them with than C# then you should consider using them. By using one language you exclude a lot of other great libraries and frameworks out there, and this case it was the difference between taking one week to build in Python as opposed to a month in C#. Do you think it is acceptable to understand and use only only one language at a startup or even a larger company? Am I perhaps being naive??

  • Interview Questions in OOP

    - by Fero
    Hi all, I faced the below interview questions in OOP under PHP language. Kindly clear my clarifications regarding this. I am very confused. As i am a beginner to OOP i got too confused. Could anyone clarify these things clearly? Difference between Abstract class and interface. Interviewer : Let us consider abstract class contains three abstract methods such as a,b,c and interface contains three methods a,b,c. In this case these do the same functionality. Then why are going for abstract and why are we going for interface. Me : ? static keyword. Interviewer: We call static method without creating object by using scope resolution operator in PHP. As well as we can able to call concrete methods also. Then what is need of static keyword there? Me : .... final keyword. Interviewer: Give me any scenario of using final keyword. Me : For db connection related method Interviewer: Other than that? Me: ... Constructor. Interviewer: What is the use of constructor? Me : There is no need for object to access this. It will call automatically when the class calls. Interviewer: Other than that? Me : .... Thanks in advance...

  • On Mac OS X how can I monitor what is using my internet connection?

    - by Jon Hopkins
    I've got a relatively limited broadband connection (I live miles from the nearest exchange) and from time to time net access (but nothing else) slows to a near crawl. I know from a bit of monitoring software that the connection is being fairly heavily used which would explain it but I don't know what's using it. There are certainly plenty of things which might (these days there are dozens of apps that will either regularly or infrequently check data or download updates) but how can I find out? I'm happy to pay (a small amount of) money if needed, though in that case I'd rather it were a recommendation that me just Googling for something.

  • What if you've been asked to develop a site and the client later introduces Ts&Cs that you'll breach whilst doing your job?

    - by Matt Lacey
    Disclaimer : this is all made up. Honest. And it represents no clients or employers living or dead, blah blah blah, etc. [Allegedly] As part of a website I've built, I've now been provided the Terms and Conditions of site usage to display on the site. These terms--which must be agreed to to access the site--include my (or any visitor to the sites) compliance with a number of clauses. Many of these clauses refer to general computer use and are not tied specifically to use of the site. Some of these clauses refer to things I have had to previously do as a legitimate part of my job and would expect to have to do again. When I've raised similar issues previously my line manager has said just to ignore it but that doesn't seem to be the professional thing to do. So, what do I do? Abiding by the terms would mean that I could no longer work on the project and would cause issues with my employer and the owner of the business the site is being created for. Ignoring them could lead to possible future issues with the business owner and is not something I'm necessarily happy with (the deliberate breaking of a legal contract). Neither option is one I'd choose and could have major consequences. Any thoughts?
